Abstract
A reclosable package comprising front and rear panels extending between top and bottom transverse seals, the front panel having a line or lines of weakened tear resistance for forming an opening, through which a zipper can be accessed. The zipper is suspended from the top transverse seal and attached to the front panel at a lower elevation. At least a major portion of the base strip of a forward zipper part is disposed between the front panel and the base strip of a rearward zipper part. Respective upper portions of the zipper base strips are joined to each other in the top transverse seal. A lower portion of the base strip of the forward zipper part is joined to the front panel in a transverse band-shaped zone of joinder. No portion of the base strip of the rearward zipper part is joined to the rear panel outside of the top transverse seal.
